Just a few comments. Received the ePlate on Monday and have been playing with it quite a bit. As an ePods (did everything introduced at the end of the 20th century start with a lowercase "e"?) owner, its impossible not to compare the two.
Seems like the SH4 processor is a good bit peppier even though it is rated at the same speed as the ePods' MIPS. Great for multi-tasking e.g. playing MP3s while note taking, and it even seems to be faster rendering web pages over a wireless connection (using a D-Link card), but I'm not sure the lack of software compiled for the SH4 processor is a reasonable tradeoff. Nearly every application that I've tried to install on it seems to lack support for the SH4.
Now that Hitachi stopped producing it, I'm not sure if the ePlate user community is going to see very many new Windows CE applications being released, which is unfortunate because, at the price I paid for it, this is a pretty nice device.
One other thing. I've been in contact with a tech support rep at Hitachi Service USA concerning a couple of issues with the screen and am VERY impressed with their level of service. Quick email responses and genuinely knowledgable about the ePlate. I can't tell you how many times I've talked to tech support guys that had never HEARD of the very product that I was calling about.
